PUMP.V

SPECIFICATION forming part of Letters Patent'No. 531,175, dated December 18, 1894.

Application led April Z7, 1894,.

. following to bea full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to improvements in that class of lift and force pumps which comprise an outer casing, a barrel or cylinder arranged within the casing, upwardly-opening valves arranged in the space between the cylinder or barrel and the casing, a valve arranged over the induction opening, and a reciprocatory plunger movable in the barrel or cylinder; and it consists in the peculiarconstruction, novel combination and adaptation of parts hereinafter described and specifically pointed ont in the claim appended.

ln the accompanying drawings Figure 1, is a vertical, central, sectional view of my improved pump with parts at top and bottom broken away. Fig. 2, is a cross sectional View taken in the plane indicated by the dotted line c, w, on Fig. 1. Fig. 3,is a perspective view of the valves removed from their seats,

and Fig. 4, is a similar view of the valved seating disk or plate removed.

Referring byletter to said drawingsz-A, indicates the stock or casing. This casing may be made of metal or other suitable material, and comprises an upper section a, and a lower section b. Each section is provided at its contiguous end with a lateral lflange c, and d, having suitable apertures for the reception of connecting bolts e, threaded to receive nuts f, or other suitable fasteningfdevices, so that while the sections -are firmly connected, they may be readily. taken apart when desired. The lower vsection b, of this casing is provided with an internal, horizontal wall or fixed plate B, having a central, vertical aperture g, of a diameter which will be presently described. Below this apertured wall B, is a chamber h, and lin the bottom of the chamber isa central, vertical aperture fi, of a diameter greater than theaperture g, of the wall above, and this aperture fi, is screw tapped as shown, to receive the upper screw Serial No. 509,259. (No model.)

lthreaded end of a suction pipe C. The upper section a, of this upper casing, is of a diameter corresponding to that of the lower section,

and its upper en d is contracted as` shown at inder or pipe D, and the discharge nozzle has a bore of a diameter as large as the discharge aperture which is larger than the valve K, presently described. r

It will thus be seen that a valve or other part of the internal mechanism which may be drawn through the cylinder or pipe D, can be removed tothe discharge nozzle without disconnecting the parts, and this is very desirable in removing the ball valve, as will be presently described.

. F, indicates a metallic plate or disk which is of a form and construction better shown in Fig. 4., of the drawings. This plate has a central, internally-threaded aperture n. Surrounding this central aperture are radial apertures p, and surrounding these radial apertures is a iiange q, which is designed to be interposed between the two lateral fianges c, and d, of the casing section, and receive the bolts which connect said sections. This valve plate or disk F, is thus firmly secured to the casing but may be readily removed when desired. Said plate receives and supports the vvertically-disposed plunger cylinder G. This plunger cylinder is externally threaded at its lower end to engage the threads in the eye or aperture of the plate F, and is of a diameter the same or about the same as the cylinder D, and is arranged directly below the latter.

H, indicates the plunger, which maybe of a suitable construction and is placed within the cylinder G, on the lower end of the plunger rod I, as shown.

K, indicates a ball valve. This valve is designed to close the aperture g, in the horizontal wall B, and in order to insure its proper seating, it may carry an internal weight r. This valve may also be provided with an eye IOG s, to receive a hook, string, or other means by which it may be drawn up through the plunger cylinder G, through the cylinder D, and out through the discharge nozzle, when desired.

Closing the apertures p, of the plate F, are valves L, and for the sake of eheapness in manufacture, these valves are cut from a single piece of leather, rubber, or other suitable flexible material, and may be made by taking a circular piece of material, cutting a circular hole in the middle to be placed over the plunger cylinder, and then slitting the material radially, as shown at t, so as to form the segmental valves L, and leave an annular portion fa, to be seated upon and secured to the upper side of the threaded ring or apertured portion n, of the plate F, so that said valves may be allowed a lifting movement. The fiange q, of the plate extends suiicientlywithin the casing A, as to also furnish a seat or bearing for the free edges of the valves L.

Although the several valves L, are formed by one piece of rubber or the like, it will be seen that each valve is capable of moving independent of the others and is consequently adapted to give upwardly when subjected to a slight pressure of water. It will furthermore be. perceived that the valves L, being independent of each other, the choking or other impairment of one or more will not interfere with the succcessful operation of the others.

By the provision of the chamber h, below the ball valve it is obvious that a number of small supply pipes connected to drive wells may be led thereto so that the water can be taken from the well while the large central suction pipe may be used in drawing water from open wells, lakes, reservoirs, and the like.

From the construction described, it will be seen thatI have a pump which may be manufactured at a comparatively small expense,

`lower casing section, the pipe D, larger in diameter than the valve K, and detachably connected at its lower end to the upper casing section a, and also having the discharge spout E, which is larger in diameter than `said valve K, the plate or disk F, interposed and secured between the flanges of the casing sections a, b, and having the central, internally threaded aperture fa, and the circular series of apertures p, surrounding said aperture n, the plunger cylinder G, larger in diameter than the valve K, and about lthe same size as the pipe, D and threaded at its lower end and screwed into the aperture n, of the plate F, a piece of rubber or other suitable material surrounding the plunger cylinder and having the annular portion secured to the upper side of the disk or plate F, and the several, independently-movable segmental valves L, arranged over the apertures p, ot' said disk or plate F, and the plunger adapted to move in the plunger cylinder, all substantially as and for the purpose specitied.

In testimony whereof Iaflix my signature in presence oi two witnesses.
